摘要： A dowel, arranged to secure an article to the surface of a receiving material having a hollow space within it into which the dowel extends, is formed of an axially elongated dowel body and a flange member at one end of the dowel body. The flange member includes a flange part extending transversely outwardly of the dowel body. The dowel body is formed from a strip of material and includes an end part extending transversely of the axial direction of the dowel body with a threaded opening through the end part, and a pair of axially extending legs divided into webs and extending in the axial direction of the dowel body from the end part. Inwardly directed recesses are formed in the ends of the legs spaced from the end part. The flange member includes a sleeve-shaped projection extending generally perpendicularly of the flange part. The sleeve-shaped projection fits into the ends of the legs, and the dowel body and flange member are welded together at the locations where the recesses in the legs contact the sleeve-shaped projection on the flange member.

摘要： An angle-shaped support member consists of a unitary element formed into a pair of legs extending normally to one another and interconnected at their adjacent ends by an outwardly extending rectangularly shaped box section. The opposite ends of the legs from the box section each have an outwardly directed flange. The flanges and walls of the box section have axially aligned openings through which bars can be fitted. The openings in the flanges and walls are offset laterally relative to one another to avoid any interference between the bars which extend through them.

摘要： The retention value of a screw previously inserted into a wooden railroad tie is increased by an axially extending sleeve ( 20 ) having an external thread ( 24 ) and an internal thread (25). The thread revolutions of the internal thread (25) are offset axially by half (h) the thread pitch (H) of the external thread (24). Due to this offset of the threads, the screw is positioned in the sleeve so that its threads are located between the external thread revolutions affording a new retention, while the external thread (24) seats within the thread previously formed in the wooden railroad tie by the screw.
